public Autodesk.AutoCAD.Interop.AcadApplication vAcadApp;

            vAcadApp = new AcadApplication();
           
            vAcadApp.Visible = true;
            
            vAcadApp.WindowState = Autodesk.AutoCAD.Interop.Common.AcWindowState.acMax;
            
            vAcadApp.Documents.Open(FileName, null, null);  // filename = test.dwg

Your code is runnig 64-bit and you're trying to load a 32-bit component. You cannot mix 32- and 64-bit code in the same process. Go into your project properties on the Compile tab and change the Target from AnyCPU to x86. This forces your app to run 32-bit only, and hence will work with 32-bit components.

Then try reversing it. Change it to x64.

the same error seem that i have to use a newer autocad 2012/2013 to be fully compatible with win 64bit
